Graduate Research Opportunities

We are looking for graduate students with background in CS theory (formal methods, logic, automata theory, algorithms) and/or control theory. Solid programming skills & other mathematical background (e.g. stochastic processes) would be a plus. As an graduate researcher you will develop new verification and synthesis algorithms, build tools, and perform experiments in using these tools on real systems.

Undergraduate Research Opportunities

We are looking for juniors/seniors with solid programming skills (E.g., C/C++, Java, Matlab) and who intend to go to grad school in one of the related research areas. Preference will be given to those who can commit to working at least 6-8 hours a week for a couple of semesters. You will work closely with one of the graduate students towards developing software tools or applying them to verify a systems. This typically leads to an undergraduate thesis or publishable work. Take a look at some of the research projects.
